A listric fault is a type of normal fault that has a concave-upward shape with the upper section near Earth's surface being steeper, becoming more horizontal with increased depth. Normal faults can evolve into listric faults with the fault plane curving into the Earth.

Dip is defined as the angle of the fault relative to the surface of the earth, which indicates the plane on which slip will occur. Lastly, in any non-vertical fault, the block above the fault is called the hanging wall, while the blockbelow the fault is called the footwall. [4] Normal and reverse dip-slip faults with labeled hanging wall and ...
A raised fault block bounded by normal faults. hot spring A natural spring resulting from the emergence of geothermally heated groundwater from beneath the Earth's crust. hydrothermal Pertaining to the actions or products of heated water. hydrothermal vent A fissure in a planet's surface from which geothermally heated water emerges. hypersaline
Strike-slip faults are associated with dominantly horizontal movement, leading to relatively simple linear zones of surface rupture where the fault is a simple planar structure. However, many strike-slip faults are formed of overlapping segments, leading to complex zones of normal or reverse faulting depending on the nature of the overlap.
The Almanor Fault Zone contains both strike-slip faults, where the earth moves from side to side; and “normal” faults, “where there’s extension in the crust, so things are being pulled ...
Earthquakes associated with normal faults are generally less than magnitude 7. Maximum magnitudes along many normal faults are even more limited because many of them are located along spreading centers, as in Iceland, where the thickness of the brittle layer is only about six kilometres (3.7 mi).
